There is Supernatural also a debate about the number of separate types of belief. Thereby, reported here is the development and Religion validation of a new multidimensional questionnaire measure of scientifically unsubstantiated beliefs in the Conspiracy general UK population. Scientifically unsubstantiated Method & results: In Study 1, participants (N = 393) completed a questionnaire containing a pool of 82 items Belief questionnaire covering nine facets of belief discernible conceptually within the existing research literature. Scree analysis followed by exploratory factor analysis indicated the existence of four empirically observable factors: belief in supernatural forces; belief in God and destiny; belief in alien visitation, monsters and conspiracies; and belief in consciousness beyond the body. Twenty-four items were selected as measures of these factors. Studies 2, 3 and 4 demonstrated the convergent and divergent validity of the four empirically-derived questionnaire subscales and their internal reliability. Conclusion: The resultant new Multi-dimensional Questionnaire of Scientifically Unsubstantiated Beliefs (MQSUB) is a psychometrically robust measure and comprises a comprehensive framework which can be used to systematically investigate the psychological and social concomitants of such beliefs. 1.
